[Asymmetric radial keratotomy for low-grade myopia]

Thirty patients (47 eyes) underwent a radial keratotomy for low myopia (from -0.75 to -2.5 D). Surgical technique was as follows: optical zone between 3.0 and 4.5 mm according to the degree of the myopia; two radial incisions in vertical superior and nasal horizontal meridian. The incisions were full thickness, obtained either with the "Russian" (centripetal) technique or with a centrifugal technique, but using a special designed knife. Mean refractive result was 1.73 D. For low myopia, our technique seems less traumatic and the refractive effect more rapidly steady.
